if (error) {
TRACE_ERROR("MCI SendCommand: Failed to send command (%d)\n\r", error);
return SD_ERROR_DRIVER;
}
// Wait for command to complete (if no callback defined)
if (pCommand->callback == 0) {
while (!MCI_IsTxComplete((MciCmd *)pCommand)); <----------------卡在这里，不熟这块芯片，有没有大神知道什么原因？ 珍惜生命，远离ATMEL。。。
